<![CDATA[This study was motivated by the limited use of interactive learning media in Natural and Social Sciences (IPAS) lessons at several elementary schools, which left fifth-grade students passive and reliant on conventional resources such as textbooks and static pictures when studying the Ecosystem Harmony topic. Using a Research and Development approach guided by the ADDIE model (analysis, design, development, implementation, and evaluation), this study produced a Canva-based interactive quiz medium that embeds the Balinese local wisdom of Tri Hita Karana, which emphasizes balance among humans, God, and nature, into the ecosystem material. Validation involved material, media, and language experts, while practicality testing involved two fifth-grade teachers and twenty students from two elementary schools in Cluster VII, Sukasada District. Data were gathered through observation, interviews, documentation, and questionnaires, then analyzed using Aiken's V for content validity and a mean-percentage formula for practicality. The findings show that the material, media, and language validity coefficients each reached 0.90, categorized as highly valid, while the practicality scores reached 89 percent from teachers and 93 percent from students, both categorized as highly practical. These results indicate that the Tri Hita Karana-based interactive quiz medium is feasible for use as an alternative learning tool for the Ecosystem Harmony topic in fifth-grade IPAS instruction.]]>
